<p>The inventive technology, in embodiments, may be described as a socket adaptor featuring automatic conformance to a tube (e.g., the inner surfaces of the end of a tube) upon the application of weight to the adaptor (e.g., to a plunger thereof), thereby allowing the secure connection of one tube to another tube in fast, effective manner. Certain guitar case embodiments involve the use of a curved panel with holes (voids) so as to create a controlled flex pattern in order to controllably dissipate impact forces applied to the front of the guitar case. Ribs may be used to provide additional structure and impact resistance.</p> |
